For all figures, observations are on the top panels (A, B, C) and abundance estimates on the bottom panels (D, E, F). The lines represent the aircraft transects, while the dots show the observations of both individual and groups. Each observation plot shows the number of sightings and the total number of individuals detected. The estimated abundance over the whole area, with the 95% confidence intervals, is also shown for the estimation plots. Left panels present visual monitoring, centre panels low-altitude digital monitoring, and right panels high-altitude digital monitoring.
